Did a post a while ago on glasses in Hitchcock here and thought it might be fun to look at glasses and the tropes they call up in Gotham.
Ed’s probably the first character who springs to mind when you think of glasses. In season one, his glasses represent three aspects of his personality: his ‘geeky’ social awkwardness; his analytical intelligence and eye for detail, and his ability to be clinical and detached.
It’s interesting that when we see Ed’s mirror self, he isn’t wearing glasses. This reinforces the image of Ed in glasses as the butt of jokes, the geeky kid. MirrorEd is frustrated by Ed’s lack of agression and his many social failures and embodies all the confidence that Ed, at this point, cannot manifest (he presumably doesn’t lack it: if his mirror self has it - it’s just buried). His hair is more stylish, his posture is better, his voice is deeper, and - noticeably - the glasses are gone.
